Online cleaning system for central air conditioner condenser

Abstract

The invention discloses an online cleaning system for a central air conditioner condenser. The online cleaning system comprises a ball loading device 1, the condenser 19 and a ball receiver 7, the two ends of the condenser 19 communicate with a cooling pipeline 20, rubber balls are arranged in an upper container of the ball loading device 1, and a water inlet 14, a ball return opening 15 and a ball outlet 16 are arranged. A pipeline, communicating with the cooling water pipeline 20, of the water inlet 14 is a water inlet pipeline. A spraying opening of a ball spryer 8 is inserted into the cooling water pipeline 20 at an inlet of the condenser 19. The online cleaning system is characterized in that a branch 11 is arranged on a ball return pipeline and a cooling water return pipeline, a check valve 403 is arranged in the branch 11, and a screen mesh 10 is arranged between the branch 11 and a ball recycling pipeline. The online cleaning system has the following beneficial effect that the rubber balls are not likely to block a ball recycling outlet. The rubber balls and garbage are not extruded on a ball recycling screen mesh, the rubber ball recycling rate reaches 100%, it is ensured that each pipeline of the condenser is cleaned in place, and it is guaranteed that the inner pipe wall of the condenser is clean all the time.

Description

technical field [0001] The invention relates to a cleaning system for cleaning a condenser in a central air conditioner, especially for cleaning pipes of a heat exchanger used in the condenser. Background technique [0002] Central air-conditioning chillers are used more and more widely as the main cold source of buildings. Many high-rise buildings and communication buildings use chillers as the cold source of computer rooms. As the air-conditioning system is a high-energy-consuming device, according to statistics, the energy consumption of air-conditioning accounts for more than 50% of the energy consumption of buildings. As the main energy-consuming unit of the air-conditioning system, the cooling efficiency of chillers is the most concerned issue for users. Especially for the condenser as the main heat exchange equipment, its heat exchange effect will directly affect the cooling efficiency and operating energy consumption of the air conditioner. Since the circulating cool...

AI Technical Summary

Problems solved by technology

When dirt is formed on the surface of the condenser, the total heat transfer resistance of the condenser increases, resulting in an increase in the logarithmic mean heat transfer temperature difference, that is, an increase in the condensation temperature, which makes the heat transfer effect of the condenser decrease under the same conditions, and leading to a decrease in the performance of the chiller

The accumulation of dirt in the condenser, on the one hand, reduces the heat exchange efficiency of the condenser and the cooling efficiency of the main unit, which greatly increases the power consumption of the air conditioner main unit

On the other hand, the increase of the fouling layer increases the pressure drop of the condenser, which makes it necessary to increase the cooling water flow and increase the energy consumption of the water pump under the condition that the cooling demand remains unchanged.
